Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of preservation box, especially a kind of plastic preservation box. BACKGROUND

[0002] Preservation box is not only convenient and practical, but also can store food by category, which can isolate food as much as possible, prevent cross contamination, prevent moisture from being released, play a sealing role, prevent food from losing original fresh taste during storage, isolate air, prevent food from being infected by oxidation. The current preservation box is composed of square box body and buckle cover, which is slippery and square in whole during carrying, which can cause the preservation box to slip and fall to the ground, and further affect the placed items in the preservation box. SUMMARY

[0003] Therefore, the utility model aims at overcoming the defects in the prior art, and provides a plastic preservation box.

[0004] The utility model provides a plastic preservation box, including the barrel -shaped box body 1, the box body 1 is connected with box cover 2 on screw thread, the box body 1 lower end's front and rear two sides symmetry is provided with the side recess 3 of arc shape, the bottom of box body 1 coaxially is provided with bottom ring 4, the outer wall of the box body 1 upper end is provided with the annular projection 5 of the box cover 2 abutment.

[0005] Further, the edge of the side recess 3 is provided with a rounded corner.

[0006] Further, the outer wall of the lower end of the box body 1 and the side recess 3 are both subjected to frosted treatment.

[0007] Further, the cross section of the annular projection 5 is in a right angle bending shape.

[0008] Further, the outer wall of the box cover 2 is uniformly distributed with arc-shaped protrusions 2.1 along its axis.

[0009] Further, the top end of the box cover 2 is recessed in the middle to form an upper circular groove 2.2, and the bottom of the upper circular groove 2.2 is provided with a bottom groove 2.3 in a track shape.

[0010] The advantages of this invention are as follows: the barrel-shaped box body is easy to grip and stable, and the arched side grooves make it more comfortable and effortless to hold, preventing slippage; the threaded connection ensures a tight connection between the lid and the box body, extending the preservation time and preventing soiling of surrounding items; the symmetrical side groove design also provides a certain degree of stability when the food storage box is placed on a flat surface; the bottom ring can horizontally support the food storage box; the right-angle bent annular protrusion tightly abuts against the lid, forming an additional sealing barrier; the rounded corners reduce stress concentration and facilitate demolding in injection molding machines, while also giving it an overall aesthetically pleasing appearance; the frosted finish creates tiny pits and particles, resulting in a frosted texture that makes the product look more upscale and of higher quality, and the frosted finish also increases the friction of the food storage box, making it more stable during use, less prone to slippage, and improving safety; the arc-shaped protrusion increases friction, allowing the lid to be screwed on; the inner wall corresponding to the upper circular groove fits snugly against the inner wall of the box body, thus achieving a good sealing effect.

[0012] Fig. 2 This is a schematic diagram of the structure of this utility model;

[0013] Fig. 3 This is the front view of the present invention. Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0016] See Figs. 1-3The utility model provides a kind of plastic preservation box, it includes barrel-shaped box body 1, barrel-shaped box body has larger internal space, and when holding, hand feel comfortable, easy to grip stable, not easy to slip, box cover 2 is threadedly connected on box body 1, threadedly connected mode makes the connection tightness of box cover and box body good, prolongs preservation time and avoids soiling surrounding article, the front and rear sides of box body 1 lower end are symmetrically provided with arched side recess 3, the design of arched side recess not only increases the beauty and uniqueness of box body, can provide natural placement position for finger when handheld, comply with ergonomics principle, make holding more comfortable, labor-saving, and can prevent slipping, simultaneously, symmetric side recess design also makes that preservation box is placed on plane with certain stability, bottom ring 4 is coaxially arranged on the bottom of box body 1, bottom ring can support the preservation box horizontally, the outer wall of the upper end of box body 1 is provided with annular projection 5 that is abutted with box cover 2, the section of annular projection 5 is right angle bending shape, right angle bending shape annular projection is tightly abutted with cup cover, forms an additional sealed defense line.

[0017] The edge of side recess 3 is provided with rounded corner. Rounded corner setting reduces stress concentration, and is favorable to injection molding machine demoulding, and whole appearance is elegant and atmospheric.

[0018] The outer wall of the lower end of box body 1, side recess 3 are all ground sand treatment. After ground sand treatment, small pit and particle are formed, ground sand texture is formed, this texture makes product look more high-grade, more quality feeling, and ground sand treatment can increase the friction of preservation box, make it more stable in use process, not easy to slip, improve the security of use.

[0019] Referring to Fig. 1 The outer wall of box cover 2 is uniformly distributed with arc-shaped projection 2.1 along its axis. The arc-shaped projection can increase the friction to facilitate the screwing of the box cover through the arc-shaped projection.

[0020] The middle of the top end of box cover 2 is concave to form an upper circular groove 2.2, and the bottom of the upper circular groove 2.2 is provided with a bottom groove 2.3 in the shape of a racetrack. The corresponding inner wall of the upper circular groove can fit the inner wall of the box body, thereby achieving good sealing effect.

[0021] The above is only preferred embodiment of the utility model, it should be pointed out, for ordinary skilled person in the prior art, on the premise of not departing from the technical principle of the utility model, can make a number of improvements and refinements, these improvements and refinements also should be regarded as the protection scope of the utility model.
